Insane Bloating from Tirz

Summary

Why does Tirzepatide cause stomach bloating even while eating less and losing weight?

One user switched from Reta to Tirz for better weight loss results but now experiences persistent bloating that prevents sucking in their stomach. Others note bloating is uncommon with GLP drugs but can stem from slowed gastric emptying or gut motility, and suggest lowering the dose, using digestive aids like GasX or Milk of Magnesia, or avoiding high-fat foods. Personal episodes were resolved quickly with over-the-counter remedies and did not recur.

Whether the bloating originates in the stomach versus lower intestines or how long it typically lasts

Nothing here is advice.

I switched from Reta because it had no effect and I was gaining weight. Tirz has been working well for weight loss but the bloating is intense. I used to pull my stomach in automatically yet now that feels impossible, and my belly protrudes more than before starting any GLP even though I eat far less and stay in a deficit.

Bloating does not come up often with these drugs, though it is frequent with various gut problems such as IBS. If nausea or changes in bowel habits are also present it could still trace back to the medication. Reducing the next dose is the straightforward step, or postponing it a few days if the discomfort is strong. Smaller meals and limiting fluids during eating are standard tips. The sensation might come from delayed stomach emptying or from gas in the lower gut due to slower movement, and location can help tell which.

Certain foods affect me the same way others have described. High-fat or greasy items leave me feeling like a rock sits in my stomach. A quick search shows why that happens.

I went through one similar episode early on Tirz and used Milk of Magnesia to empty everything, which fixed it in a few hours. It has not returned since, though I keep GasX ready just in case. Hopefully this is a single occurrence for you as well. GasX would have been the milder choice at the time.

Peppermint gels or another digestive aid taken with meals. Also kpv.
